Hi Imran daud shah,

We can get AZ1 and AZ2 Azimuth direction from two ways.

First way -  AZ1 and AZ2 is perpendicular by center point (O) to P1 line. So we will know AZ1 and AZ2 azimuth direction.

Second way - If you using AUTO Cad , can measure angle direct from North line 0 degree to AZ1 and AZ2 line.
